Absolutely David's number should be retired. He has been one of the best and most feared hitters in the league since 2003, even with the down 2008 and 2009 years. Plus, he was a huge part of both world series. There is not a reason to not retire his number here other than alleged ped charges. Jim Rice has his number retired here, as he should being a hofer, and papi has more impressive hitting stats than him. You can't deny Papi.
